2Jn_1:12-13. JOY FULFILLED:CHILDREN OF THE ELECT SISTER. SALUTATION.
The likeness of these two epistles indicates that both were by one writer, and in each case the internal evidence supports the traditional belief that both were written by the apostle John. Several of the early "fathers" quote the Second Epistle, certain passages of which so closely resemble parts of the First Epistle as to confirm the view of its being by the same writer.
The Second Epistle is addressed "unto the elect lady and her children", and some have understood a certain church and its members Alford, however, gives good grounds for believing that an individual is meant.
